Caleb Martin’s injury wasn’t as bad as feared, but the Nevada men’s basketball team suffered another significant blow last week when junior point guard Lindsey Drew ruptured his right Achilles tendon during a win over Boise State.

The victory all but assured Nevada (23-5, 12-2 Mountain West) of winning a second consecutive MW regular-season title. The Wolf Pack has a 1 ½-game lead over second-place Boise State (21-6, 11-4) with two weeks left in the regular season. Nevada has four games remaining, and Boise State has three, beginning with a Wednesday night game at CSU (11-17. 4-11).

In its first game without Drew, who averaged 8.1 points, 4.1 rebounds and 4.3 assists a game, the Wolf Pack won 93-87 Saturday at Utah State. But his loss will certainly hurt the team’s chances of winning the MW tournament or receiving a decent seed in the NCAA tournament if it doesn’t, despite a No. 20 ranking this week in the Associated Press poll and No. 9 RPI. ESPN analyst Joe Lunardi had Nevada as a No. 8 seed in his latest projection Monday.

Martin, the MW’s leading scorer at 19.6 points a game, was expected to miss six to eight weeks with a Lisfranc sprain in his left foot. But he has continued to play since suffering the injury in the first half of a Feb. 7 loss at UNLV and scored 23 points in 35 minutes in Saturday’s win at Utah State.

Here are this week’s complete MW power rankings:

1. Nevada (23-5, 12-2 MW)

Last week: 1. RPI: 9. Nevada’s roster continues to shrink, with just seven scholarship players available the rest of the season while four others sit out under NCAA transfer rules. But the Wolf Pack keeps winning and only plays one of its final four regular-season games against a team in the top six of the conference standings.

2. Boise State (21-6, 11-4 MW)

Last week: 2. RPI: 53. The Broncos got back on track after dropping back-to-back games for the first time this season — at Utah State and at home to Nevada — with a 76-52 win Saturday over visiting Air Force.

3. Fresno State (19-8, 9-5 MW)

Last week: 3. RPI: 96. The Bulldogs had two of their most-lopsided wins of the season last week over two of the MW’s worst teams, winning by 20 points Wednesday at San Jose State and by 21 at home Saturday vs. Colorado State University to extend its winning streak to four.

4. New Mexico (12-14, 8-6 MW)

Last week: 7. RPI: 185. The Lobos, who were coming off back-to-back losses to Boise State and Air Force, avenged an earlier loss to Utah State with a 78-63 win in their only game last week.

5. Wyoming (17-10, 8-6 MW)

Last week: 5. RPI: 83. The Cowboys bounced back from road losses at UNLV and San Diego State with a comfortable 89-75 win at home Saturday over San Jose State.

6. UNLV (19-8, 9-6 MW)

Last week: 4. RPI: 121. The Runnin’ Rebels’ three-game winning streak, which included a Feb. 7 win over Nevada, came to a screeching halt Saturday in a 94-56 loss at San Diego State. It was the most-lopsided win by either team in the 68-game series, yet only gave the Aztecs a season split.

7. San Diego State (15-10, 7-7 MW)

Last week: 8. RPI: 110. After losing six of their previous eight games, the Aztecs picked up two big wins at home last week against teams ahead of them in the conference standings, Wyoming on Wednesday and UNLV on Saturday.

8. Utah State (14-14, 7-8 MW)

Last week: 6. RPI: 138. The Aggies dropped both their games last week, falling 78-63 at New Mexico and 93-87 at home to Nevada.

9. Air Force (10-15, 4-9 MW)

Last week: 9. RPI: 235. Air Force followed up its second set of back-to-back wins this season with losses last week at UNLV and Boise State.

10. CSU (11-17, 4-11 MW)

Last week: 10. RPI: 215. The Rams, playing under their third coach this season while Larry Eustachy and Steve Barnes are on paid administrative leave, lost 86-65 at Fresno State on Saturday in their only game last week. The Rams, who have three regular-season games remaining, have lost eight of their past nine.

11. San Jose State (3-22, 0-14 MW)

Last week: 11. RPI: 307. Losses to Fresno State at home and Wyoming on the road last week extended the Spartans’ losing streak to 14 straight games.
